Eduardo thinks of a number between 1 and 20 that has exactly 5 factors. What number is he thinking of?

1 answer:

4 0

It is the number 16 because it has exactly five factors which are : 1,2,4,8,16. The number 4 repeats itself, therefore it is count as one number.

Hope this helps

20 because 12 divided by 3 is 4. then you multiply 5 by 4. and you get 20.

What is the probability that it is not blue?

Alisiya [41]

1/3 chances the bubblegum is blue. To solve this problem you add all of the bubblegum together so 25+20+15 to get 60 then express it as a fraction to show only the blue pieces which would be 20/60 and you can simplify it to 1/3 or 33.33%

Which statement explains the difference between a point and a vertex please fast

dlinn [17]

The difference between point and the vertx is that a vertex can be used to create different geometric shapes and a point is always part of the shape.

Step-by-step explanation:

Though Vertex and Point sound similar, they are different in many crude aspects. Vertex is defined as the meeting point of two sides, lines or any extended parts. The point, in turn, denotes the singular identity of a place.

Hence vertex can be used to draw any geometrical pattern. It can be done by extending or protruding the given body parts which would result in a new geometrical figure.

Points would constitute every part of that geometrical surface that we wish to identify.

Help solve this please

Answer:

a) 2

b) - $\frac{1}{2}$

c) y = 2x + 1

Step-by-step explanation:

First put the equation into slope intersept form (y=mx+b) by...

Move the variable to the right-hand side and change its sign : -y = -4 -2x

Change the signs on both sides of the equation: y = 4 + 2x

Use the commutative property to reorder the terms : y = 2x + 4

Slope intersept form : y = 2x + 4

Parallel lines have the same slope so.... a parallel slope is 2

First put the equation into slope intersept form (y=mx+b) by...

Move the variable to the right-hand side and change its sign : -y = -4 -2x

Change the signs on both sides of the equation: y = 4 + 2x

Use the commutative property to reorder the terms : y = 2x + 4

Slope intersept form : y = 2x + 4

To find a perpendicular slope flip the slope and change the sign : - $\frac{1}{2}$

First put the equation into slope intersept form (y=mx+b) by...

Move the variable to the right-hand side and change its sign : -y = -4 -2x

Change the signs on both sides of the equation: y = 4 + 2x

Use the commutative property to reorder the terms : y = 2x + 4

Slope intersept form : y = 2x + 4, parellel slope : 2

Substitute the x and y values with the given ordered pair: 3 = 2(1) + b
Calculate the product: 3 = 2 + b
Move the variable to the left-hand side and change its sign: -x = 2 - 3

Calculate the difference and change the signs : b = 1

Use the slope and y-intersept (b) to write the new line : y = 2x + 4
